The bandwidth held is 20MHz；The supported bandwidth of 802.11n STA is 40MHz；802.11ac the supported bandwidth of STA is
80MHz or 160MHz.Therefore, the available channel bandwidth of each MU-MIMO group can due to STA minimum channel bandwidth therein and by
Limit.
Although high-speed wideband wireless environment can provide broader bandwidth, actual channel bandwidth still can be by with minimum channel band

123 belong to same MU-MIMO group.As shown in Figure 1A, when MU-MIMO group (including STA 121~123) is movable (active) shape
When state, channel 3 only used.That is, channel 1~2 and channel 4~8 are not used by and are wasted.So not making sufficiently
Use radio resource.
In addition, cannot effectively be managed with old-fashioned eclipsed form BSS (overlap BSS, OBSS) the 802.11ac AP coexisted
Manage its channel.Figure 1B, which is shown, cannot initiatively manage its channel since AP coexists with old-fashioned OBSS.As shown in Figure 1B, 802.11ac
AP can support channel 1~8,131 busy channel 3 (such as channel of 20MHz) of OBSS, 132 busy channel 5~6 of OBSS
(40MHz), they can prevent 802.11ac AP from obtaining broader channel.Although combinable 8 channels of 802.11acAP are to start
One BSS, but there is only 2 available continuous channels (40MHz).

Specific embodiment
The present invention discloses a kind of method and system for managing wireless network, wherein the wireless network has at least one AP
With multiple movement stations.
In following, broadband AP (wide Band Access Point, WBAP) expression can support that (n is n narrow band channel
Natural number) wireless aps.Narrow band channel can such as 20MHz.Moreover, AP can be coordination wireless communication device (coordinating
wireless communications device)；STA can be wireless communication device.Channel of operation indicates to include one or more
The channel of a non-overlap (non-overlapping) narrow band channel.And non-overlapping operation channel table show not with other channel of operation
The channel of operation of the narrow band channel of overlapping.
AP, which merges, can use narrow band channel to form the BSS for supporting broad-band channel and select a narrow band channel as main channel.
AP and STA manages and controls information by main channel exchange cordless communication network.And AP is narrow according to the selection of the first preset rules
Band channel is as main channel.After AP selects main channel, AP states (announce) main channel to all STA.
Multiple narrow band channels are divided into one group of non-overlapping operation channel by the first preset rules, and for example, first is default
Rule is according to the parameter selected from parameter group, wherein the parameter group includes the useful number of narrow band channel, each narrowband letter
The narrow band channel that the interference level (level of the interference) in road and each STA are supported.
The bandwidth of broad-band channel is determined by AP according to channel condition and AP/STA capacity.All STA of BSS receive AP and send
One or more duplications beacon (duplicated beacon), wherein this one or more duplication beacons are covered to broad-band channel.
In addition, further disclosing a kind of MU DL frequency domain multiplexing (frequency domain in exposure of the invention
Multiplexing, FDM).AP manages the channel selection of member STA (member STA), and wherein member STA may include old-fashioned
STA (such as 802.11b/g/n STA) and new-type STA (such as 802.11ac STA).Each new-type STA is grasped to non-overlap is formed
One group of narrow band channel for making channel is operated, wherein this group of narrow band channel includes one or more narrow band channels.And one or more
Non-overlapping operation channel can carry out parallel work-flow.
STA tissue (organize) is the communication set greater than one by AP.It is narrow to occupy one or more by STA in each communication set
Band channel, and the communication set that should be greater than one is located on the narrowband (reside).Wherein, the composition of each communication set
(constituent) it is either statically or dynamically determined by AP according to the second preset rules.AP adaptability recombinates (re-organize)
STA is to improve the performance of cordless communication network.
Second preset rules determine the composition of each communication set and determination distributes STA to which non-overlapping operation channel,
Second preset rules are according to the algorithm selected from parameter group, wherein the parameter group includes optimal adaptation algorithm, adapts to calculate for the first time
The number (population of non-overlapping operating channel) of STA in method, non-overlapping operation channel
And multiple application requirements (application requirement).
The channel width that AP is occupied according to parameter change communication set, wherein parameter can such as bandwidth utilization rate and communication
The bandwidth demand of the application program configured in group.
The STA of communication set greater than one also can not carry out parallel work-flow under the direct management of AP.In other words, from
The data transmission of STA to other STA is direct exchanges or by AP transfer (relay).
AP indicates the STA of communication set from a band displacement (migrate) to another frequency band.
It will now be described how establishing channel of operation and STA group.
WBAP is embedded in radio frames (radio frame) (such as beacon) or management frame by sending on the primary channel
Invitation message (invitation message) is to STA, or unsolicited requirement message (unsolicited is received from STA
Requesting message) Lai Jianli cordless communication network.Beacon is repeated on each narrow band channel that AP is supported.
The association (association) and certification of the transmission starting STA of the reception or requirement message of invitation message
(authentication) process (STA can occupy m narrow band channel, and wherein m is natural number and m≤n).STA is exchanged with AP
Cordless communication network is added after capacity (capability) information and completes association and verification process.
According to preset allocation algorithm, WBAP indicates that STA occupies p narrow band channel, and wherein p is natural number and p≤m≤n.
STA exchanges management message with WBAP using main channel.
If first addition architecture (infrastructure) wireless network of STA, the example allocation of WBAP use
Algorithm can be first-fit algorithm, that is, WBAP selection has WBAP and STA first group of continuous p of minimal noise amount narrow
Band channel.The also adoptable example allocation algorithm of WBAP can be optimal adaptation algorithm.
If the infrastructure wireless networks with q STA (q is natural number) are added in STA, for example, WBAP can basis
Some factors either statically or dynamically determine channel distribution, wherein these factors include: channel of operation participation (occupant) number,
The bandwidth consumption of narrow band channel number, active flow (active flow) that each STA is supported is (in one embodiment, movable
The bandwidth consumption of stream is service quality (Quality of Service, the QoS) setting based on communication stream) and channel of operation
Overall load.For example, WBAP can distribute 40MHz STA to occupancy if infrastructure wireless networks are added in 40MHz STA
The STA group of 40MHz or 80MHz generates smaller influence with the overall load on channel of operation.
In one embodiment, n narrow band channel can be divided into r (r is natural number) according to the first preset rules by WBAP
STA is simultaneously divided into s group (s is natural number) by a non-overlapping operation channel.
For example, 160MHz can be divided into the non-overlapping operation channel of (1) two 80MHz by WBAP；(2) 80MHz are non-
The non-overlapping operation channel of overlap operation channel and two 40MHz；(3) 80MHz non-overlapping operation channels, a 40MHz
Non-overlapping operation channel and two 20MHz non-overlapping operation channel；(4) 80MHz non-overlapping operation channels and four
The non-overlapping operation channel of 20MHz；The non-overlapping operation channel of (5) four 40MHz；The non-overlapping operation letter of (6) three 40MHz
The non-overlapping operation channel in road and two 20MHz；The non-overlapping operation channel of (7) two 40MHz and the non-overlap of four 20MHz
Channel of operation；The non-overlapping operation channel of (8) 40MHz and the non-overlapping operation channel of six 20MHz；(9) eight 20MHz
Non-overlapping operation channel.The channel width of non-overlapping operation channel can be similar and different.In addition, the STA number in each STA group
Mesh can be similar and different.
In another embodiment, STA formation group, wherein STA channel capacity of each group of the channel width by each group
It determines, or is determined by AP.If the summation of all groups of channel width is greater than n narrow band channel, WBAP is according to each group
QoS demand determines the channel width of each non-overlapping operation channel, and the channel width summation of all non-overlapping operation channels must
The summation of n narrow band channel must be equal to or less than, on the contrary, if no more than n narrowband letter of the summation of all groups of channel width
Road then determines each group of channel width according to the channel capacity of each group of STA.
In yet another embodiment, if one of STA known to WBAP and one or more other STA establish direct chain
Connect session (direct link session), i.e., message directly exchanged between a STA and one or more other STA without
WBAP is passed through in transfer, then WBAP can determine to repartition (re-partition) n narrow band channel and be the STA and (have with it
Having and directly link session) one or more other STA establish non-overlapping operation channel.For example, n narrow band channel be again
Division can be according to above-mentioned partitioning algorithm (partitioning algorithm).And in the presence of side as known to those skilled in the art
Method in time migrates the multiple STA directly linked to newly-installed channel of operation.
In yet another embodiment, WBAP can know from the QoS of communication stream setting (occupies one or more greater than one group
Channel of operation) STA intercourses data, i.e., and data (ping-pong fashion) in the form of rattling are sent out between two STA
Send data.For example, the exchange that the exchange or data/confirmation (acknowledge) of demand/respond packet (packet) are grouped.
WBAP is that exclusive times section (dedicated time is arranged in (occupying one or more channel of operation) STA greater than one group
Period) to access (scheduled access) for the scheduling of wireless channel.Channel of operation can be synchronized and be operated.
The STA data exchange of channel of operation will now be described.
It for the message in a channel of operation, can directly be swapped between the STA for occupying the channel of operation, or logical
Cross WBAP transfer.One message can be sent to a STA (i.e. unicast) in channel of operation, or be sent to one or more STA
(i.e. multicast), or it is sent to all STA (broadcasting).And it can be by WBAP from the message that a STA is sent in channel of operation
Go to another STA in different operation channel.The operation of WBAP coordination non-overlapping operation channel.Non-overlapping operation channel and
Row operation can be carried out either synchronously or asynchronously.
When STA, which has, prepares the data to other STA, STA can be by (1) according to the association of such as 802.11 CSMA/CA
View competes (contend) access right (access right) (carrier sense (carrier sensing avoided collision
Collision avoidance) realization), or by (2) request WBAP authorize access right (namely based on the realization of request),
Or the mixing of aforementioned two kinds realizations is combined to realize by (3).In other words, in exposure of the invention, there is at least three
The implementation method of kind channel access.
When the STA of non-overlapping operation channel carrys out access wireless channel for example, by above-mentioned channel access implementation method, and
When no WBAP synchronizes the channel access of the channel access and other non-overlapping operation channels, between non-overlapping operation channel
Carry out asynchronous operation.Otherwise, the non-overlapping operation channel and other channel of operation synchronize operation.
WBAP is that each non-overlapping operation channel decides whether should to synchronize or different according to one or more coordination systems
Step operation.In a coordination system, WBAP is placed on one of them asynchronous behaviour for the multiple STA groups for directly linking session are established
In the channel of operation of work.Remaining channel of operation synchronizes operation by WBAP coordination.
In addition, in this embodiment, AP can provide MU DL flow by some realizations, these realize to include MU DL-
MIMO, MU DL-FMD or MU DL-OFDMA.
To realize that MU DL-MIMO, AP select the subset (sub-set) of merged channel to operate for DL-MIMO.
For realize MU DL-FDM, AP instruction target (target) STA convert to respective channels and by DL flow be sent to respective channels with
For load balance.To realize that MU DL-OFDMA, AP select the subset of merged channel for based on DL-MIMO's
